Treatment of Infected uncemented Total Hip Arthroplasty: Two-stage revision procedure by preserving well-fixed femoral components in four cases / 대한정형외과학회잡지

In infected uncemented hip arthroplasty, 4 cases which showed well-fixed femoral stem were managed by staged procedure. Thorough debridement, removal of acetabular socket and insertion of antibiotics impregnated cement spacer was done without removal of femoral stem. No recurrence of infection or loosening was developed after staged procedure and revisoin was performed after infection evidence disappeared. The interval between the two procedures was 4 months (3-6) on average. In Weber's criteria, all 4 cases were graded as having definitive cure of infection on both clinical and radiological criteria (Grade I) .

Surgical Traetment of Ischiogluteal Bursitis: 3 cases report / 대한정형외과학회잡지

Ischiogluteal bursitis is a cause of buttock pain. Patients, who have ischiogluteal bursitis, usually have painful swelling over the center of the buttock and down the back of the leg. Ischiogluteal bursitis is frequently confused with many other causes of lower extremity buttock pain because of its anatomical characteristics. Generally, conservative treatment for ischiogloteal bursitis is usually sufficient. However, some severe cases with chronic painful ischiogluteal bursitis necessitates surgical treatment. Few reports describe the surgical treatment for this condition. The authors report 3 cases of chronic ischiogluteal bursitis who were successfully treated with surgical bursectomy.

Parapatellar Complications after ACL Reconstruction Using Bone-Patellar Tendon-Bone Autograft / 대한정형외과학회잡지

PURPOSE: To evaluate clinical and radiological results and to analyse the parapatellar complications after endoscopic anterior cruciate ligament reconstruction using central one-third bone-patellar tendon-bone autografts. MATERIALS AND METHODS: 66 cases among 158 consecutive cases from Feb 1990 to May 1996 were reviewed and evaluated with regard to patellofemoral pain, crepitus, quadriceps atrophy, graft donor site complication, Lysholm knee scoring system and radiological assessment. The average period of follow up was 23 months (range, 12-57 months) and the average age at operation was 31 years old (range, 18-58 years). RESULTS: The average Lysholmn knee score improved from 57.5 points preoperatively to 91.3 points at follow up. The instrumented anterior laxity test showed that excellent anterior stability was regained in most patients. There were many cases of parapatellar complications, 7 cases (10.6%) of anterior knee pain, 21 cases (32.8%) of crepitus, 43 cases (65.1%) of quadriceps weakness, 29 cases (45.3%) of graft donor site paresthesia and 15 cases (23.4%) of pain on kneeling. CONCLUSIONS: Although endoscopic ACL reconstruction using central one-third bone-patellar tendon-bone autografts had good clinical results, many parapatellar complications were noted. In order to prevent these complications, different reconstruction techniques and graft materials should be considered
